Loves mariachis/has had mariachis on special occasions or while being drunk: Yes.
Well, yes, but who hasn't?
A life without tacos is an empty life: Yup, I love my country's gastronomy and it goes waaaaaay farther than just tacos, burritos, chimichangas and quesadillas so yeah, tremendous stereotype on this one.
I have heard once of a delicacy in Mexico that comes from the rare times when a bead of rainwater enter the husk of an ear of corn, resulting in a fungus on the interior. The fungus is supposed to be astoundingly tasty, but I cannot remember the name of it.
Chamuca, PLEASE tell me you know what the name of this thing is?
